<p><P>PROBLEM TO BE SOLVED: To provide a vibration-isolating device of a steering shaft capable of preventing the characteristics of a bush and a dynamic damper from being affected by each other when both of them are mounted. <P>SOLUTION: The vibration-isolating device of the steering shaft comprises an inner cylindrical member 11 which has a cylindrical shape and is pressure-fitted to an outer circumferential surface of a first shaft member 2 of a steering shaft, a first outer cylindrical member 12 which has a cylindrical shape, and is arranged separately from the inner cylindrical member 11 outwardly in the radial direction, and press-fitted to an inner circumferential surface of a second hollow shaft member 3 of the steering shaft, a second outer cylindrical member 13 which has a cylindrical shape and is arranged separately from the inner cylindrical member 11 outwardly in the radial direction and arranged separately from the first outer cylindrical member 12 in the axial direction, a mass member 14 fitted to an outer circumferential surface of the second outer cylindrical member 13, a bush rubber 15 for elastically connecting an outer circumferential surface of the inner cylindrical member 11 to an inner circumferential surface of the first outer cylindrical member 12, and a damper rubber 16 for elastically connecting the outer circumferential surface of the inner cylindrical member 11 to the inner circumferential surface of the second outer cylindrical member 13. <P>COPYRIGHT: (C)2009,JPO&INPIT</p> |
